css - How can I reset the <div> class name? -

-

i have velocity template code generating class name on basis of loop. possible reset div name when 1 of loop iteration not match criteria. code have written:

  #set ($size = $confs.size())   #set ( $prev = "mycontent" )   #foreach($i in [0..$size])    #if($i < $size)             </br>     <table>         <tbody>            <tr class="impact-soy" data-key="$confs.get($i).impact">                <div class=impact-$i>                   <span>$confs.get($i).impact</span>               </div>                      #if($prev != $confs.get($i).actor)                   <div class=actors-$i style="margin-left: auto; margin-right: auto;">                       <span>$confs.get($i).actor</span>                       #set ($prev = $confs.get($i).actor)                   </div>                    #else                    #end                <script>                    $(document).ready(function() {                         $('div.impact-$i').connections({ from: 'div.actors-$i' }).length;                       var connections = $('connection, inner');                       setinterval(function() { connections.connections('update') }, 100);                   });               </script>            </tr>          </tbody>         </table>         #end         #end

else block should reset class name previous if block executed class name.

you can :

 #set ($prev = "test")    <div class=actors-$i>          #if($prev != $confs.get($i).actor)                  <span>$confs.get($i).actor</span>                  #set ($prev = $confs.get($i).actor)         #else             //do nothing , reset div class previous true //valid condition             $('.actor-'+$i).addclass('true'+$i);             $('.true'+$i).removeclass('actor-'+$i).addclass('actor-'+($i-1));          #end   </div>
